The ‘Parameterize NETLink …’ button takes you to a new input
form that already contains the current parameters of the NET-
Link
®
:
If no NETLink
®
Gateway can be accessed via the stated IP address,
the following message will appear:
This message can have two causes:
• There is no NETLink
®
device with the stated IP address (e.g. the
device has not yet been switched on or is still starting up).
• The IP configuration of the computer used does not match the
IP configuration of the stated NETLink
®
(e.g. different subnet
mask settings).
From the parameterization form shown, it can be seen that not
only static IP address allocation but also IP parameter assignment
via DHCP is possible.
Both these options are now explained in more detail.
5.2.3 Operation without the DHCP
If a NETLink
®
is used in a network without a DHCP server (or you
want the NETLink
®
to work with the same IP address on the
network despite the presence of a DHCP server) the required IP
parameters are stored in the input forms for ‘Static parameters.’
In this case, the checkmark is not set in the field ‘Get IP address
automatically (DHCP).’
Clicking the ‘Save in NETLink PRO Family’ button saves the pa-
rameters in the NETLink
®
Gateway.
